PCB Modeling

Lower Grasse River, New York Managed the creation of a GIS database of existing field data on the Grasse River.  Performed data analyses aimed at determining PCB sources to the river and the processes governing the fate and transport of PCBs throughout the study area.  Compiled and analyzed laboratory data generated from semi-permeable membrane device (SPMD) experiments conducted independently, calculated uptake rates for individual PCB congeners, and applied those rates to field data collected from the Grasse River.
Upper Hudson River, New York Responsible for updating and managing a GIS database for spatial analyses of PCB measurements.  Performed data analyses aimed at determining PCB sources to the river and the processes governing the fate and transport of PCBs throughout the study area.  Tasks included assisting in the contaminant modeling effort with model input development, graphical display of data, and analysis of PCB distributions and PCB fate mechanisms within the Upper Hudson River.
Lower Hudson River, New York Designed, coordinated, and performed two SPMD field studies to determine spatial differences in PCB concentrations with decreasing proximity to the upper river PCB source.  Performed extensive data analyses aimed at elucidating the fate of PCBs in the river.
Kalamazoo River, Michigan Managed data analyses utilizing GIS to evaluate the contribution of PCBs from two paper facilities to the Kalamazoo River.  Compiled and analyzed historical data.
Little Mississinewa River, Massachusetts Managed historical data compilation and analyses utilizing GIS to evaluate the contribution of PCBs from a small motor manufacturing facility to the river.  Determined PCB sources through the evaluation of congener-specific PCB patterns.
Former Waste Fuel Storage Facility, New Jersey Reviewed and evaluated several expert reports and data sets to examine the spatial distribution and composition of PCBs in the soil and groundwater to determine PCB sources.

Water Quality Monitoring

PCB Analysis, Hudson River, New York Responsible for construction and maintenance of a database containing QA/QC data generated during PCB analysis of weekly water samples.  Performed regular validation of the data to evaluate its usability and produce qualifiers for inclusion into the database.  Identified problems in data quality and offered solutions so that data quality objectives could be met.
Quality Assurance Planning, Hudson River, New York Managed the development of a quality assurance project plan for a water column and fish sampling program to establish baseline conditions in advance of sediment remediation.  Oversaw the development of an automated data validation system.

Modeling

North Sandy Pond, Oswego County, New York Assisted in the development of a combined watershed/water quality model for North Sandy Pond, located off of Lake Ontario.  This project included the implementation and customization of EPA's Better Assessment Science for Point and Non-point Sources Program (BASINS) to simulate the impact of nutrient loadings to the lake.  Responsibilities included development of model parameters and loadings and application of the model to the study area.
Southern California Bight, California Compiled and organized available DDT data in mussels of the Southern California Bight.  Performed data analysis using GIS to facilitate spatial analyses to study sources and pathways by which DDE entered the bight.
Androscoggin River, Maine Reviewed and critiqued a final total maximum daily load (TMDL) document issued by the State of Maine.  This study involved the analysis of data to provide a paper manufacturing company with the information necessary to evaluate deficiencies in the TMDL document with regard to the data input into the model.  It included the development of direct and rebuttal testimony.

Litigation Support

Contaminated Site Characterization and Allocation Support, Portland Harbor, Portland, Oregon The Portland Harbor Superfund site is a complex river system with multiple parties contributing to remediation. Provided allocation support for two facilities located at the site by helping to write two expert reports summarizing forensic analyses focused on PCBs and dioxins and furans.
Sediment Superfund Site, Washington, Confidential Location Provided technical support for an industrial client in a cost allocation process. Conducted historical operations research, environmental data analysis, chemical fate and transport evaluations, and report preparation. Ongoing matter.
Urban Waterway and Sediment Superfund Site, New York Provided project management and technical support for multiple parties concerning defense of contaminated sediment liability for their alleged multipathway historical contribution. Developed conceptual site models, conducted initial sediment source characterization, and constituent fate and transport analysis. Wrote a site characterization work plan.
Assessment of a Hydrocarbon Release at a Natural Gas Storage Facility, Los Angeles, California Provided technical support for a litigation case involving an insurance settlement following a large release of gas from a storage facility.
